Lion Field (about six or seven kilometers away from Bishan County in the direction of Qinggang on Biqing Road) and Riverside Field (about ten kilometers away from Bishan County in the direction of Tongliang on Bitong Road), these two are the closest, and other places like Dalu and Liutang are twenty or thirty kilometers away.

it's definitely ok to set up a stall, otherwise it won't be a rush.

In principle, the municipal government will not collect money for setting up stalls in these places, but if the place you occupy is someone's site (such as the open space in front of people's facade), it depends on whether people collect money.
